The application's requirement is submitted to Korea S Department of Intellectual Property, the applying date is the priority of the korean patent application No.2006-0004205 on January 24th, 2006, and it is in full by being incorporated herein by reference.
Technical field
The present invention relates to a kind of refrigerating chamber, comprise the refrigerator of this refrigerating chamber, and control method.More specifically, the method that the present invention relates to a kind of refrigerator and be used to control this refrigerator, wherein said refrigerator comprises independently refrigerating chamber, this refrigerating chamber can the supercooling beverage and is kept the supercooled state of beverage, and described method makes the variations in temperature in the refrigerating chamber be reduced to minimum, so that keep the supercooled state of beverage.
Background technology
Along with the development of refrigerator technology, ice cream formula beverage has satisfied the demand of people for good to eat cold drink at first, and this beverage makes with chilled beverage in refrigerator; Recently, satisfy demand to good to eat cold drink partly to freeze formula beverage (below be referred to as " half jelly beverage "), this beverage has the middle phase between the ice cream of the beverage of liquid phase and solid phase, and can make by bland and ice pellets.
For conventional refrigerator, make half jelly beverage by mixing required beverage and trash ice.Yet, be inconvenient to drink because the ice pellets size is big, therefore this half jelly beverage can not fully satisfy user's needs, and this half jelly beverage passes by easily in time and diluted, and this causes the taste of beverage to change.
Therefore, consider the demand that satisfies the user, be necessary to provide a kind of half jelly beverage, it is not easy diluted, and comprises even, the tiny ice pellets that is suitable for this half jelly beverage in this half jelly beverage.According to well-known technology, can make this half jelly beverage by following method: with the beverage supercooling to its freezing point or low temperature more, so that be not in frozen state, add ice-nucleus subsequently or apply and impact or vibration, so that the beverage that is in supercooled state is freezed.
Meanwhile, in making the process of this half jelly beverage, thus must be with the beverage supercooling to its freezing point or the lower frozen state that is not in, and must keep the supercooled state of beverage.
Usually, under the atmospheric pressure, at 0 ℃ or following, the phase transformation of from liquid to the solid (i.e. ice) can take place in water.In some cases, water does not undergo phase transition, but exists with supercooled state.When water was in supercooled state, owing to have higher free energy than solid water, the water that therefore is in supercooled state was to also unstable.At this, term " free energy " is meant along with predetermined chemical reaction carries out continuously and can realize the energy of effective merit.According to the second law of thermodynamics, system isolated on any thermodynamics is tending towards along with the time develops to low-energy state from upper state.Therefore, with regard to free energy, chemical reaction carries out along the direction that reduces free energy.
In other words, under the atmospheric pressure, in freezing point or more under the low temperature, water is in supercooled state and uncongealable this state is called as metastable state on thermodynamics.When beverage was in metastable state, beverage neither was in poised state and also is not in complete labile state.Therefore, if there is external disturbance, beverage can undergo phase transition at once, changes more stable phase into from supercooled state---ice.That is, supercooled beverage freezes.As a result, extremely difficult beverage is remained on supercooled state.
In theory, allow pure water to be in supercooled state and uncongealable minimum temperature is approximately-40 ℃.Yet experience shows that under the temperature of this theoretical temperatures, water will freeze.
In this regard, when allowing water being lower than to be in supercooled state under the temperature of freezing point and uncongealable temperature range when being defined as degree of supercooling is understood easily, different with theoretical degree of supercooling, in fact the degree of supercooling of aqueous drink very little.That is to say, rule of thumb can understand that it is very narrow to make beverage be in the temperature range of supercooled state, and beverage can freeze immediately when temperature is lower than freezing point slightly.
According to above-mentioned viewpoint, for conventional refrigerator, it is very difficult making half jelly beverage by the supercooling beverage.Particularly, because contained material difference, every kind of beverage has the degree of supercooling different with Other Drinks, so just is difficult to every kind of beverage is remained in the supercooled state.In addition,, also be difficult to keep have the supercooled state of some beverage of low degree of supercooling even the degree of supercooling of all beverages is provided, this be owing to conventional refrigerator because of the inhomogeneous variations in temperature that relative broad range takes place of circulating cold air in it.
In addition, even beverage can remain on supercooled state, but owing to taking a long time supercooled beverage for making half jelly beverage, therefore, the user need wait and obtain half jelly beverage for a long time.
